SPECIFICATION forming part of Letters Patent No. 773,072, dated October 25, 1904.

i Application led May 19, 1904. Serial No. 208,649. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM GRIFFIN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Whistling-Tops, of which the following is a specication. p

My invention relates to tops ofthat type which are spun by the complete unwinding thereon and* disconnectiontherefrom of a string as the top is thrown forcibly to the ground; and my object is to produce a top of this character which produces a Whistling sound as long as the rapid spinning motion continues. A further object is to produce a top of this character of simple, cheap, and durable construction.

With these objects in view the invention con- Y sists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed, and in order that it. maybe fully understood reference is-to be had to the accompanying drawings, in which- Figure l is aperspective View of a top embodying my invention'. Fig. 2 is a vertical section taken on the line II II of Fig. l. Fig. 3 is a horizontal section taken on the line III III of Fig. 2. Figs. 4 and 5 are plan views, partly in section, of modified forms of construction.

In the said drawings, l designates an ordinary top adapted to be spun in the usual manner.

2 designates a hole, lpreferably circular, which is bored into the top and opens. through one side of the same, said hole being preferably f'ormed near the point of greatest diameter of the top.

3 designates a sleeve fitting snugly in said hole andprovid'ed with a vertical slot 4, registering with the opening through the side of the top, that margin of the slot 4 which points in the direction in which the top spins projecting slightly beyond the plane of motion of the other margin, as at 5, so that as the top spins in thedirection indicated by thefarrow said projecting margin 5 of the slot shall cut the wind and cause the latter to produce a whistling sound, which sound will continue as long as the top is in rapid motion. One end of the sleeve is closed by the base of the hole 2 and the other by the plug 6, fitting and glued or otherwise rigidly secured inthat portion of the hole projecting beyond the sleeve, though of course said plug may be of integral formation with the sleeve.

If desired, the top may be of the construction shown in Fig. 4, .which figure discloses Vno sleeve,but simply the hole 2,with that marintegral formation with the body of the top,

as will be readily understood.

' In Fig. 5 the hole 2 is shown as horizontal and oblique to a radial line, the front margin 9 of the opening being nearer the axis of motion than the rear margin lO for a reason eX- plained in connection with the other types of construction. i

From the above description it will be apparent that I have produced a whistlingltop which embodies the features of advantage enumerated as desirable and which is obviously susceptible of modification without departing from the essential spirit and scope or sacrificing any of its advantages(` Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A top having a hole opening out through f its side, and a sleeve fitting in said hole and formed with a slot registering with said opening, and having the rear margin of its slot projecting outward beyond the plane of its Vopposite margin.

2. A top having a hole opening out through its side, a sleeve fitting in said hole and formed with a slot registering with said opening, and having the rear margin of its slot projecting outward beyond the plane of its opposite margin, and a plug fitting in said hole and closing the proximate end `of the sleeve.

In testimony whereof I aiiix my signature in the presence of two witnesses.

WILLIAM GRIFFIN. Witnesses:
